(現(xiàn)代設(shè)計集團華東建筑設(shè)計研究院有限公司，上海200002)[摘要] 我國現(xiàn)行《混凝土結(jié)構(gòu)設(shè)計規(guī)范》采用 η-l0方法設(shè)計偏心受壓構(gòu)件，該方法對長細比大于30的細長柱誤差較大。為解決此問題，本文在“模型柱”理論研究基礎(chǔ)上，提出偏壓細長柱設(shè)計方法，并進行了模型試驗驗證。該設(shè)計方法應(yīng)用于實際工程中，取得了良好的效果。

( East China Architecture Design Institution, Shanghai 200002, China)Abstract: It cannot give enough precision when the method adopted by current code for design of concrete structures is used in design of eccentric compression member with slender ratio greater than 30. Based on the theory of model column and model test verification, new method for design of eccentric compression is presented and has been well used in practical design.
Keywords: slender column; η-l0method; "model column" method; strength failure; stability failure
